Have you guys thought about working with College/Universities to give them site licenses for their staff & students to use 1Password both on Mac & PC. The reason why I mention this is my school (and I know it isn't unique) is 'obsessed' with security, forcing the students to change their passwords every 60 days (even when this has been proven to be more insecure). Additionally I know that many campuses provide students with a copy of Norton AV (or McAfee, etc) to 'protect' them from viruses.
Maybe you guys could talk to some universities and get some nice contracts with them. You could explain how using 1Password (w/dropbox) is the most secure way to generate hard-to-guess passwords and store them safely.
Just a thought.
